AndroidAnnotations学习笔记--事件续（四）
@[email protected]@OptionsItem

@OptionsMenu ：用来指定菜单资源
@OptionsMenuItem ：MenuItem的实例
@OptionsItem ：用来接收菜单的选中事件

没有上面的注解，我们要这样写代码

@EActivity(R.layout.activity_test)public class TestActivity extends Activity {		MenuItem itemhome;		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);	}		@Override    public boolean onCreateOptionsMenu(Menu menu) {        MenuInflater menuInflater = getMenuInflater();        menuInflater.inflate(com.hista.weiweilove.R.menu.mymenu, menu);        itemhome = menu.findItem(R.id.menu_home);        return super.onCreateOptionsMenu(menu);    }    	@Override	public boolean onOptionsItemSelected(MenuItem item) {		// TODO Auto-generated method stub		switch(item.getItemId()){	       case R.id.menu_home:	       	           Toast.makeText(TestActivity.this, ""+"home", Toast.LENGTH_SHORT).show();	           itemhome.setTitle("主页君");	           break;	       case R.id.menu_search:	           	           Toast.makeText(TestActivity.this, ""+"search", Toast.LENGTH_SHORT).show();	           break;	       case R.id.menu_share:	           	           Toast.makeText(TestActivity.this, ""+"share", Toast.LENGTH_SHORT).show();	           break;	       default:	    	   break;	       }			return super.onOptionsItemSelected(item);	}}

有了上面的注解我们可以这样写代码

@EActivity(R.layout.activity_test)@OptionsMenu(R.menu.mymenu)public class TestActivity extends Activity {		@OptionsMenuItem    MenuItem menu_home;		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);	}		@OptionsItem(R.id.menu_share)    void myMethod() {		// You can specify the ID in the annotation, or use the naming convention		Toast.makeText(TestActivity.this, ""+"share", Toast.LENGTH_SHORT).show();    }    @OptionsItem    void menu_home() {    	// home was selected in the action bar    	// The "Selected" keyword is optional    	Toast.makeText(TestActivity.this, ""+"home", Toast.LENGTH_SHORT).show();    	menu_home.setTitle("主页君");    }    @OptionsItem    boolean menu_search() {    	Toast.makeText(TestActivity.this, ""+"search", Toast.LENGTH_SHORT).show();    	// menuSearch was selected    	// the return type may be void or boolean (false to allow normal menu processing to proceed, true to consume it here)    	return true;   }    @OptionsItem({ R.id.menu_search, R.id.menu_share })    void multipleMenuItems() {    	// You can specify multiple menu item IDs in @OptionsItem    	Toast.makeText(TestActivity.this, ""+"search or share", Toast.LENGTH_SHORT).show();    }}

@OptionsItem({ R.id.menu_search, R.id.menu_share }) 支持多个MenuItem


@SeekBarProgressChange

在未使用这个注解前，我们要写这样的代码

@EActivity(R.layout.activity_test)public class TestActivity extends Activity {		@ViewById(R.id.tv_test)	TextView tvTest;		@ViewById	SeekBar seekbar1;	@ViewById	SeekBar seekbar2;		@UiThread	void setObject(String s){		tvTest.setText(s);	}		@AfterViews	void afterView(){				seekbar1.setOnSeekBarChangeListener(new OnSeekBarChangeListener()        {        	public void onProgressChanged(SeekBar arg0,int progress,boolean fromUser)        	{        		setObject(String.valueOf(progress));          	}        				@Override			public void onStartTrackingTouch(SeekBar seekBar) {				// TODO Auto-generated method stub				Toast.makeText(TestActivity.this, "seekbar touch stare", 100).show();			}			@Override			public void onStopTrackingTouch(SeekBar seekBar) {				// TODO Auto-generated method stub				Toast.makeText(TestActivity.this, "seekbar touch end", 100).show();			}        });    }}

使用之后我们可以这样写代码：

@EActivity(R.layout.activity_test)public class TestActivity extends Activity {		@ViewById(R.id.tv_test)	TextView tvTest;		@ViewById	SeekBar seekbar1;	@ViewById	SeekBar seekbar2;		@UiThread	void setObject(String s){		tvTest.setText(s);	}		@SeekBarProgressChange(R.id.seekbar1)	 void onProgressChangeOnSeekBar(SeekBar seekBar, int progress, boolean fromUser) {	    // Something Here		setObject(String.valueOf(progress)); 	 }	 @SeekBarProgressChange(R.id.seekbar1)	 void onProgressChangeOnSeekBar(SeekBar seekBar, int progress) {	    // Something Here		 setObject(String.valueOf(progress)); 	 }	 @SeekBarProgressChange({R.id.seekbar1, R.id.seekbar2})	 void onProgressChangeOnSeekBar(SeekBar seekBar) {	    // Something Here		 setObject(String.valueOf(seekBar.getProgress())); 	 }	 @SeekBarProgressChange({R.id.seekbar1, R.id.seekbar2})	 void onProgressChangeOnSeekBar() {	    // Something Here	 }}

@SeekBarProgressChange({R.id.seekbar1, R.id.seekbar2}) ：支持绑定多个View
同样，与前面的几个事件一样，也支持多种参数形式

原有代码书写方式见前面那个注解，这里就不重复了

有了这两个注解后，我们可以这样写代码了：

@EActivity(R.layout.activity_test)public class TestActivity extends Activity {		@ViewById(R.id.tv_test)	TextView tvTest;		@ViewById	SeekBar seekbar1;		@UiThread	void setObject(String s){		tvTest.setText(s);	}		@SeekBarTouchStart(R.id.seekbar1)	void seekbarStart(SeekBar seekBar)	{		Toast.makeText(TestActivity.this, "seekbar touch stare", 100).show();	}		@SeekBarTouchStop(R.id.seekbar1)	void seekbarStop(SeekBar seekBar)	{		Toast.makeText(TestActivity.this, "seekbar touch stop", 100).show();	}}

至这里AndroidAnnotations的事件的注解就全部结束了
